PROBLEM TO BE SOLVED: To eliminate rotation irregularity in a rotary coupling, and to reduce vibration and noise. SOLUTION: A developed profile in a circumference direction of an outer circumference part 31 is formed with a periodic wave form curve, an inner surface is formed by a spiral curved track connecting a point on the curve and a top part of a pitch corn, a yoke 3A having a spherical recession 35 on the top part of the pitch corn is attached to an input shaft and an output shaft, and a spherical body 5 is inserted into the recession 35, and thus, the rotary coupling is constituted.
